12:04 AM XXCoder: yo
12:07 AM XXCoder: miss0r: 2 axis?
12:07 AM CaptHindsight: miss0r: I've had weeks like that
12:07 AM CaptHindsight: hey fragalot
12:07 AM miss0r: XXCoder: ?
12:07 AM miss0r: CaptHindsight: me too. but its been a while
12:07 AM XXCoder: oops it was ziper who asked lol
12:07 AM CaptHindsight: oops it was
12:07 AM CaptHindsight: ziper who
12:07 AM miss0r: packing my gear & heading out to the client. see you around
12:07 AM CaptHindsight: a day without punctuation is like...
12:07 AM CaptHindsight: have fun!
12:07 AM XXCoder: later miss0r
12:08 AM XXCoder: capt you responded to ziper also :)
12:08 AM fragalot: hey
12:08 AM ziper1: oh, I guess that would depend on if the spindle is driven or not huh?
12:08 AM fragalot: miss0r: good luck, hope it won't be miss0rable today!
12:08 AM CaptHindsight: fragalot: do you guys offer service plans or extended warr on machines you build?
12:09 AM XXCoder: it seem to be controlled yeag
12:09 AM XXCoder: rather than just spin or not
12:09 AM ziper1: I kind of want to make a machine like that but I need to figure out the benefits over other methods of composite layup
12:09 AM fragalot: CaptHindsight: service plans are handled by the sales offices per country, but we do offer extended warranty from the factory where Iwork
12:10 AM CaptHindsight: fragalot: any idea of the warranty cost vs machine cost?
12:10 AM CaptHindsight: %
12:11 AM fragalot: never more than 5%, typically hovers around 2 I believe
12:12 AM CaptHindsight: ziper1: all tubes?
12:12 AM ziper1: well
12:12 AM ziper1: maybe a wing mast
12:13 AM ziper1: but I dont know how I would make that
12:13 AM ziper1: but tubes are good too
12:13 AM CaptHindsight: have a pic?
12:14 AM ziper1: like this http://www.catsailingnews.com/2017/08/a-class-worlds-2017-sopot-exploder-d3.html
12:14 AM ziper1: one problem is the track where the sail goes up the back of it
12:14 AM ziper1: I might just use off the shelf carbon anyway
12:15 AM ziper1: since that would need a big furnace and prepreg is super expensive
12:15 AM CaptHindsight: http://etamax.com.au/online-shop/images/product/dimensions_WM300_medres_2_2.png
12:16 AM ziper1: different ratio, but more or less
12:20 AM ziper1 is now known as ziper
12:21 AM CaptHindsight: ziper: with that track in the back?
12:21 AM ziper: yeah
12:22 AM ziper: its late here but i'd like to continue tomorrow
12:22 AM CaptHindsight: is the track aluminum?
12:22 AM ziper: it could be
12:22 AM ziper: traditionally the whole extrusion is aluminum
12:22 AM CaptHindsight: just heading off myself
12:22 AM CaptHindsight: CF wing with AL track
12:23 AM CaptHindsight: you could do it as a tube and wrap and then add the track
12:27 AM CaptHindsight: I'd probably make the two tubes and then wrap it into one
12:27 AM CaptHindsight: then add the track
12:27 AM CaptHindsight: i was going to make some CF printers to make auto body panels
12:27 AM CaptHindsight: anyway I'm off
01:59 AM Deejay: moin
02:00 AM gloops: hello
02:34 AM XXCoder: heys
02:35 AM Deejay: yoohooo *waving hand*
04:33 AM jthornton: morning
04:34 AM XXCoder: hey jt
04:34 AM XXCoder: tomorrow, the spacking guy comes in, and also pumbler lol
04:34 AM jthornton: what's up
04:35 AM jthornton: what are you getting plumed?
04:35 AM XXCoder: plumber lol
04:38 AM jthornton: well no rats to be seen this morning
04:38 AM XXCoder: nice
04:40 AM dave__ is now known as gloops
04:41 AM jthornton: didn't get my trap set was raining too much
04:42 AM jthornton: got the hole plugged up in the run, going to make a feeder tray cover for nights today
04:47 AM jthornton: https://imagebin.ca/v/3wPyVki9p3f5
04:47 AM jthornton: that's the run camera
04:47 AM XXCoder: RUN! RUN, SPOT, RUN!
04:48 AM XXCoder: ;)
04:48 AM XXCoder: fanastic exposure and setting
04:48 AM jthornton: that's the best camera I have a Amcrest
04:49 AM XXCoder: I kinda want to have chickens lol but no way I can take care of em well
04:49 AM XXCoder: too busy!
04:50 AM gloops: this is a useful tool, except it doesnt work in my inkscape http://verysimpledesigns.com/vectors/inkscape-tutorial-spiro-swirls.html
04:50 AM XXCoder: guide is 2009
04:50 AM jthornton: XXCoder: can you have chickens where you live?
04:51 AM XXCoder: probably not lol tacoma is big city
04:51 AM jthornton: many cities have rules like max 3 hens no rooster etc some rules are silly
04:52 AM jthornton: https://www.backyardchickens.com/articles/tacoma-washington-chicken-ordinance.61362/
04:52 AM jthornton: you can have up to 6 hens
04:54 AM XXCoder: interesting
04:54 AM XXCoder: chickens is social, so I would go for 2 minium
04:54 AM XXCoder: never only one
04:55 AM XXCoder: UK has that right
04:56 AM gloops: no rooster is mainly about noise, my mate along the road had one a couple of years ago on his garden, dont really notice it in the day, its just at daybreak mainly lol
04:57 AM jthornton: mine will start crowing at the neighbors roosters and go on for a while
04:58 AM jthornton: https://www.backyardchickens.com/threads/calling-any-one-from-missouri.73271/page-872
04:58 AM jthornton: scroll down to post #8720
04:59 AM jthornton: I'd like to have a Sebright or two but they can't sex them when they hatch
04:59 AM XXCoder: buy 8 of em
05:00 AM XXCoder: probabity is that in least one of em will be gender you want.
05:00 AM XXCoder: and rest well nice mealtimes when they ready
05:01 AM jthornton: https://www.cacklehatchery.com/silver-sebright-bantam.html
05:01 AM jthornton: you get them in multiples of 5
05:03 AM gloops: the silver ones are nice yeah, if bred true, you can sometimes get the fertile eggs on ebay
05:06 AM jthornton: I'd just get some day old from Cackle Hatchery
05:06 AM gloops: https://www.ebay.co.uk/itm/12-X-SILVER-SEBRIGHT-HATCHING-EGGS-TOP-EXHIBITION-STRAIN/253523504148?
05:07 AM gloops: bit of messing about hatching yeah, unless you have an incubator
05:07 AM XXCoder: monochromic birds heh
05:07 AM gloops: you can guarantee the day the eggs arrive is the day your broody decides she aint broody no more
05:07 AM XXCoder: only color is red
05:07 AM jthornton: wow that is an expensive egg
05:08 AM gloops: for 12 - £1 each, thats actually not bad for those, they dont lay many
05:08 AM jthornton: I missed that it was for 12 eggs
05:09 AM jthornton: I thought 12 X was part of the name lol
05:09 AM gloops: maybe hatch 6, then heat them for 6 weeks, feed them for 12, might be worth £15 each adult
05:11 AM gloops: some really pretty bantams sometimes come up for sale, i forget all the names now
05:13 AM gloops: https://i.pinimg.com/originals/fc/a7/2f/fca72ffa934a0fba40039b92815420fe.jpg lol
05:14 AM jthornton: my neighbor has some like that but slightly different color
05:16 AM gloops: ive got a silkie sitting on 7 eggs, could be interesting if they hatch, 1 white polish cockerel, one red sultan in with the hens who knows whats gonna come out
05:19 AM gloops: right before i do anything else, going to copy the configs for this machine, done all this and never made a copy, if that hard drive fails to boot ill be crying lol
05:19 AM jthornton: I hear you
05:29 AM jthornton: I need to figure out how to cover the feeder opening automagicly at night when the coop door is closed
05:30 AM XXCoder: flip down servos?
05:32 AM jthornton: yea some kind of motor to open and close a L shaped cover over the opening
05:38 AM Tom_L: looks like all is well in chickenville
05:39 AM jthornton: so far the door opens in 11 minutes
05:43 AM XXCoder: jthornton: would be nice to make it loose, but automically falls down. so it can lift and hold up, but as it flips down it simply follows it
05:43 AM XXCoder: that way default is closed
05:43 AM XXCoder: also would not break on a chicken if it stays out as door closes
05:43 AM XXCoder: (whats chances on that?)
05:44 AM jthornton: the coop door or the feeder door
05:44 AM XXCoder: feeder door
05:45 AM jthornton: I would only close it after the coop door is closed
05:46 AM XXCoder: yeah but then I wonder if chickens would sometimes stay outside?
05:46 AM jthornton: no, they are always on the roost before sundown. The door closes at dusk
05:46 AM XXCoder: interesting
05:47 AM jthornton: chickens can't see at night so they have to find a roosting place before dusk
05:47 AM XXCoder: hmm makes sense
05:48 AM jthornton: when they were in the brooder I had extra light for them on a timer and the first night the lights went off they all just sat down... I knew then I had screwed that up lol
05:49 AM XXCoder: lol
05:49 AM jthornton: you only add light in the morning
05:51 AM XXCoder: yeah gonna work with chicken instact
05:55 AM XXCoder: wtttf https://youtu.be/owseTngZFMI
06:07 AM XXCoder: he actually did it
06:07 AM XXCoder: he made a knife with alum foil
06:07 AM jthornton: damn door lock didn't retract for some reason
06:14 AM XXCoder: wonder what happened
06:15 AM jthornton: well I did "fix" some of the code yesterday but didn't touch that section at all
06:15 AM fdarling_: would anyone be able to point me in the right direction for a boilerplate userspace HAL component in C? I am looking at example code online but there doesn't seem to be an example Makefile nor a simple example (like the passthrough Python example)
06:16 AM jthornton: best place to look is github.com/linuxcnc
06:16 AM fdarling_: yeah I was looking at that but the Makefile seems to be a Submakefile that's several levels deep
06:17 AM fdarling_: jthornton: https://bit.ly/2J01Blb
06:18 AM * jthornton runs and hides from makefiles lol
06:18 AM gloops: ive still got 2 ally plates 400x 150 that i cast lol, if ever this router actually cuts anything im going to skim them up for the next project
06:18 AM XXCoder: you do alum casting?
06:19 AM fdarling_: jthornton: I just want a "simple" Makefile that knows how to find the proper path for includes/libraries, and a minimal C file to work from
06:19 AM gloops: ive cast bits and bobs before, there was a few kg in the plates, not done anything that big before
06:20 AM fdarling_: jthornton: the LinuxCNC bundled components sourcecode seems to be designed to work from within their build system...
06:20 AM gloops: i decided to skip them and buy some plates - ironically the ones i cast are a lot stiff than the ones i bought heh
06:20 AM fdarling_: jthornton: this is in contrast to the simplicity of the Python userspace HAL API: http://linuxcnc.org/docs/html/hal/halmodule.html
06:21 AM jthornton: yea, I don't know much about make files I had to get someone else to make me one
06:21 AM fdarling_: jthornton: for compiling a HAL component, or for some other C project?
06:22 AM jthornton: to build html from asciidoc
06:23 AM jthornton: HTML = $(patsubst %.txt,%.html,$(shell find -name \*.txt))
06:23 AM jthornton: all greek to me lol
06:25 AM jthornton: for standalone C I just use gcc
06:26 AM jthornton: I wonder if I can fit a switch on the chicken door lock so the door won't open unless the lock is open
06:27 AM fdarling_: jthornton: I have actually had to write crazy Makefiles before :-S
06:28 AM fdarling_: jthornton: because the alternative is to use a build system like cmake or something, and that's always an annoying dependency to introduce into a project... so many levels of abstraction...
06:28 AM fdarling_: jthornton: it's kind of like bash scripting or Windows batch file scripting, it gets really crazy really fast
06:29 AM fdarling_: so many echo's to make sure everything is expanding correctly :-P
06:29 AM XXCoder: lol https://www.youtube.com/watch?v=MeNR0guNn70 this pasta knife cuts better than my regulkar metal one.
06:29 AM XXCoder: he also made wood one. quite good
06:31 AM jthornton: I need to add a porch to the coop and make a wider ramp
06:37 AM miss0r: What a day :]
06:37 AM miss0r: Somehow I managed to survice and even look good doing so(professionally that is, not cosmetic) :]
06:52 AM jthornton: nice
06:58 AM gloops: bought 1 trend router £1 - actually felt a bit sorry for the kid as worth more than that, didnt arrive so i thought yeah he isnt going to post that for £1 - didnt leave any feedback, others did saying items not arrived - turned up today hes sent 2 lol, never been opened
06:59 AM gloops: router cutter
07:00 AM jthornton: V cutter?
07:02 AM gloops: ballnose 3.2 mm
07:02 AM gloops: CO50
07:06 AM gloops: https://www.trenddirectuk.com/12-31x1-4tc
07:07 AM gloops: new trend cutters come up for auction all the time here, dunno if its people who work at trend or what
07:53 AM jthornton: I think the door lock is fried...
07:53 AM gregcnc_: smart house won't let you out?
07:56 AM JT-Shop: coop door lock
07:59 AM JT-Shop: https://www.amazon.com/gp/product/B00AOCAETQ
08:39 AM JT-Shop: damn rain... I've so much outside work to do and can't do any of it
08:43 AM gloops: weather is crap here, very late winter, now its raining all the time
08:53 AM IchGucksLive: hi
08:53 AM IchGucksLive: rain outsiide
08:53 AM IchGucksLive: gloops: inline ?
11:11 AM gloops: https://www.mirror.co.uk/news/uk-news/one-largest-wildcats-ever-recorded-12265508 wouldnt like to stick my hand in a hole and that was in it
11:22 AM fragalot: hi
11:28 AM IchGucksLive: hi
11:28 AM fragalot: hey IchGucksLive
11:28 AM IchGucksLive: ;-)
11:39 AM jthornton-: what the hell the door lock works now...
11:40 AM Tom_L: i think the chickens got your number
11:40 AM Tom_L: they're just messin with ya
11:40 AM Tom_L: loose wire?
11:40 AM Tom_L: wet?
12:00 PM gregcnc_: odd machine https://www.ebay.com/itm/263573040660
12:02 PM Tom_L: maybe for prototypes
12:03 PM IchGucksLive: gloops: ?
12:03 PM gloops: yes?
12:03 PM fragalot: Tom_L: or dental?
12:03 PM IchGucksLive: can you explane me short whats about the cricket AU
12:03 PM gregcnc_: dental is all 5x now
12:03 PM fragalot: IchGucksLive: they cheated.
12:04 PM IchGucksLive: how can you cheet in a gentle sport
12:04 PM fragalot: IchGucksLive: they put something on the ball to change it's trajectory
12:04 PM gloops: Ichs - scratching the ball - make defect on surface - ball bounces off bat randomly
12:05 PM gloops: you can clean the ball or polish it to make it shiny but not damage the surface
12:05 PM IchGucksLive: does the ball need to be on the ground bevor hidding the bar
12:05 PM gregcnc_: I http://cameronmicrodrillpress.com/micro-cnc-machines/cnc-micro-machining-center-tc/
12:06 PM IchGucksLive: gregcnc_: 25k costs with all
12:06 PM Rab: *Axis resolution is 0.0001” (.0025mm) * Axis repeatability is 0.0002” (0.005mm)
12:06 PM Rab: * Spindle run out is less than 2 micron (78.74 microinches)
12:06 PM gloops: the ball doesnt have to bounce - i dont think, it usually does though
12:06 PM gregcnc_: standard stuff
12:07 PM Tom_L: sorta like inflating footballs too much?
12:07 PM Tom_L: or not enough
12:08 PM gloops: doesnt have to bounce off the floor before hitting the wicket - you can in theory send it straight at the wicket, but mostly get called a no ball
12:11 PM IchGucksLive: Rab: they work on 0,5mm bits in Ceran
12:19 PM IchGucksLive: im off Gn8
12:26 PM gloops: nice mess about with the gas, laying new pipes in the street and to every house, every day they turn the gas off at the mains they have to come and light the boiler again - which is whenever they happen to turn up
12:30 PM fragalot: does your boiler not have a button to do it yourself?
12:31 PM gloops: something has to be lit - or alight, only a registered person can do it - or at least they have to check something anyway
12:32 PM gloops: i didnt think boilers had pilot lights these days
12:32 PM fragalot: older ones do
12:33 PM gloops: its not that old, about 3 years
12:33 PM fragalot: my water heater lights itself, but the livingroom heater has a clicky button to switch on the pilot light manually
12:34 PM gloops: funny actually ive never known this, you can turn the gas off at the meter and you dont have to do anything with the boiler
12:34 PM gloops: dunno some regulation i suppose
12:34 PM fragalot: glad I don't live in the UK then :P
12:34 PM fragalot: I like being able to manage my own things
12:35 PM fragalot: the only thing I can't do is gas piping
12:35 PM gloops: will be health and safety - anyones house goes up after theyve gone home it wont look good
12:37 PM Tom_L: fragalot sure you can, just don't tell em
12:39 PM fragalot: Tom_L: need an inspection certificate that they want when they come to take the readings periodically
12:39 PM gloops: they got really keen with here, been some pretty bad explosions
12:40 PM fragalot: I do know how, probably better than most contractors (sadly), but.. eh.
12:40 PM fragalot: it's not like you need to run a new gas line every day :p
12:40 PM gloops: not so bad if it leaks in the street, even if it ignites its just a big blowtorch
12:41 PM Tom_L: the last inspector i had thru here was askine _me_ if it was ok on some furnace duct
12:41 PM gloops: if it leaks in the house you could have problems, fills walls cavities etc
12:42 PM fragalot: gloops: if it leaks /too much/ (there is actually an allowance for leaks, which I personally find ridiculous)
12:42 PM gloops: best way to check - a lighter
12:42 PM Tom_L: that's how i do it
12:42 PM Tom_L: that or soap
12:43 PM gloops: yeah bubbles
12:43 PM fragalot: that's if you think you know where it could be
12:43 PM gloops: the old gas man used to use matches, any suspect joints or fittings, you can hear it or smell it bad if its a bad leak
12:43 PM Tom_L: pressure test first then start with fire
12:43 PM fragalot: the only way to check properly is to pressurize the system, seal it off, and wait half an hour to see if the pressure drops
12:44 PM gloops: they can check with a pressure gauge now
12:44 PM Tom_L: alot of times the brass pet cocks themselves leak
12:44 PM gloops: with everything off - no loss of pressure however small
12:45 PM fragalot: gloops: an alternative accepted method that's slower is to switch off all gas devices, and look at the meter over the period of 1 hr
12:45 PM Tom_L: it would have to be a pretty good leak
12:45 PM Tom_L: i would think
12:46 PM fragalot: Tom_L: like I said - officially some leakage is acceptable
12:46 PM Tom_L: i'd rather have none
12:46 PM fragalot: yup
12:46 PM gloops: a common con here was to turn the meter round lol, i think thats why smart meters where so unpopular
12:47 PM Rab: gloops, that, and their deadly radiation emissions.
12:48 PM gloops: and also they can record your conversations apparently and monitor your facebook messages
12:48 PM Rab: Indeed. They also trigger headaches and schizophrenic episodes.
12:49 PM Rab: And inform the authorities about your grow-op.
12:49 PM Rab: (That last one's true.)
12:49 PM gloops: clever way to do it, little box in some closet out of sight
12:50 PM fragalot: why out of sight
12:50 PM fragalot: the clever way is to use a little box that is always on someone's person, within clear view
12:50 PM gloops: theyre usually out of sight
12:50 PM fragalot: where people voluntarily enter the information you can't gather otherwise
12:50 PM gloops: they got social media for that
12:51 PM fragalot: Yup
12:51 PM nos: Is it possible to get a toolpath plot like this using a lathe spindle axis instead of a rotary axis? https://i.imgur.com/plZ7VfQ.png
12:51 PM gloops: like Person of Interest
12:52 PM gloops: just a straight diameter nos?
12:55 PM nos: No, G2 on the Z and X axis/
12:56 PM nos: I want to develop a macro to do rope threads.
12:56 PM Tom_L: you're likely going to get the plot the cutter path takes
12:56 PM nos: hmm
12:58 PM nos: My journey to insanity: https://www.cnczone.com/forums/g-code-programing/357692-g-code-processing-speed.html
12:59 PM gloops: archivist might help he does hand coding for lathe i think
01:00 PM Tom_L: skunkworks would know about plotting too i bet
01:01 PM nos: Archisvist is my beacon of hope. I don't want to lose hope in case he doesn't know. :b
01:02 PM cradek: I don't know what a rope thread is, but you can sure do spindle synced motion with g76/g33
01:02 PM nos: ...but G2 lets me do rotary axis in the same movement. Neat.
01:02 PM nos: cradek: I'm not looking to do anything sensible, like using functions for their intended purpose.
01:03 PM Tecan: https://github.com/aizquier/typewriter-sounds
01:04 PM nos: https://i.imgur.com/oM2RpeL.png
01:04 PM nos: lovely
01:05 PM nos: G2 X100 Z0 A7200 R50 F2000
01:06 PM gloops: have you tried that nos?
01:08 PM nos: You mean G2 X100 Z0 A7200 R50 F2000? Yes, it's https://i.imgur.com/oM2RpeL.png
01:08 PM nos: With GEOMETRY = CXZB
01:08 PM nos: derp
01:09 PM nos: GEOMETRY = AXYZ under [DISPLAY] in my machine ini.
01:10 PM gloops: i mean have you actually cut it on a machine?
01:11 PM nos: never
01:13 PM nos: Just a simple test to see if I can do something more complicated.
01:14 PM gloops: ok, well youll get to grips with it, i want to make a lathe of sorts but may be some time off lol
01:30 PM nos: https://i.imgur.com/K1fh3d2.png
01:30 PM nos: mmm doughnut
01:31 PM gloops: how would that work though?
01:32 PM gregcnc_: Are you turning or milling in this lathe?
01:32 PM nos: It doesn't represent the final work...
01:33 PM nos: https://i.stack.imgur.com/l3NKr.gif
01:33 PM nos: I want to make this work on a lathe, so that the spindle and circular interpolation are in synch, so that it forms a thread.
01:34 PM nos: https://www.youtube.com/watch?v=XSIcV710ACk
01:34 PM nos: like this
01:35 PM nos: but instead of stabbing in-line; using circular interpolation since oler lathes don't have the processing speed to do that is being done in the video
01:36 PM gloops: so you want to specify z movement relative to rotation
01:36 PM gregcnc_: so you do some math as if you were writing each pass of a thread idividually
01:37 PM nos: https://imgur.com/a/xkZjZ
01:38 PM nos: my code is here: https://www.cnczone.com/forums/g-code-programing/357692-g-code-processing-speed.html#post2165726
01:38 PM gregcnc_: this is to reduce the number of passes?
01:39 PM nos: This method can't succed because even if my math is right, the machine can't process it fast enough.
01:39 PM nos: I'm not sure.
01:39 PM gregcnc_: do it liek the mastercam example
01:40 PM nos: I opened my mouth on reddit, thinking I knew how it was done. Down the rabbit hole I went.
01:40 PM nos: never
01:40 PM gregcnc_: never what?
01:40 PM nos: I will do it in the most unintuitive, magical way possible.
01:41 PM nos: Or not at all.
01:41 PM gregcnc_: OK i hope you get paid by the hour
01:41 PM nos: This is not my day job. :b
01:41 PM fragalot: so you get night shift pay
01:41 PM nos: I'm a machinist, but this is for fun.
01:54 PM gloops: use the force nos
01:55 PM gloops: you may break a few tools, but its worth a go
02:05 PM nos: If I succeed, I could probably dual-license and sell it for kilobucks. >:)
02:06 PM Tom_L: what are these shapes for?
02:07 PM nos: Early attempts to can produce a toolpath which actually looks like a rope thread.
02:07 PM nos: -can
02:10 PM nos: ...Because it is a bit much to imagine.
02:10 PM fragalot: can your tool clear it properly to make it?
02:10 PM nos: A visual aid.
02:10 PM nos: https://www.youtube.com/watch?v=XSIcV710ACk
02:10 PM nos: This is a rope thread.
02:10 PM nos: https://i.stack.imgur.com/l3NKr.gif
02:11 PM nos: This is a point moving at a constant speed on a wave.
02:12 PM nos: I want to see if I can use a very fast circular interpolation in place of the oscillation in the video.
02:12 PM fragalot: Right. Enjoy. :)
02:12 PM nos: :P
02:14 PM nos: M question was if I can plot spindle rotation like the rotary axis.
02:14 PM gloops: my toolpost does that on its own haha
02:14 PM nos: That is, S and M3 instead of A.
02:15 PM nos: You mean the physical toolpost?
02:15 PM gloops: nice stuff though, the rope thread is a thing of beauty
02:15 PM gloops: nos yes its cracked
02:15 PM nos: mmh!
02:15 PM nos: ah, my condolences
02:16 PM fragalot: my compound slide cracked too, but it's very rare for me to actually use it, so instaed there is just a big chunk of tool steel to take it's place. :P
02:16 PM fragalot: worked well to make the lathe a ton more rigid too
02:18 PM nos: I think a large part of the famed rigidity of CNC machines comes from just the mass of the revolver.
02:18 PM gloops: ill see what i can do with it, got enough other things on atm
02:18 PM fragalot: nos: Quite possibly, that and the mahoosive slant bed
02:18 PM fragalot: and the goose-neck effect of the upside down tools
02:18 PM gregcnc_: hmm tha major design aspects of the entire machine
02:19 PM fragalot: gregcnc_: weird isn't it
02:19 PM fragalot: it's like someone actually sat down and thought about it
02:19 PM fragalot: gloops: on mine I just put some bolts through it sideways to clamp the crack together & drilled a small stopper hole to hopefully stop it cracking all the way through
02:20 PM fragalot: not ideal, but I don't use it enough to justify replacing it
02:20 PM fragalot: :P
02:20 PM gloops: fragalot i think its too late the crack runs from the middle of one end to about an inch away from the far end
02:20 PM fragalot: oh dear
02:20 PM fragalot: well.. at least you can't make it worse?
02:21 PM gloops: i might try welding but we all know the chances of that being a good fix
02:22 PM fragalot: good pre-heat & the right filler material is essential for it to last
02:22 PM gloops: should be able to find something i can bolt to the cross slide on ebay, some day
02:22 PM fragalot: you might be better off brazing if you have no experience welding cast
02:23 PM gloops: i have welded cast a couple of times, i thought of making a charcoal fire, warm the slide up weld it on the hot charcoal and let it cool off with the fire slowly
02:23 PM gloops: nickel rods
02:24 PM fragalot: that'd work I guess
02:24 PM gloops: ive not known anything taking that amount of stress last long - cast welded, it can work ok in some applications, structural etc
02:24 PM gloops: my experience anyway
02:25 PM fragalot: i've not had good luck welding cast myself
02:25 PM fragalot: so I stick to brazing when needed
02:25 PM gloops: its got to take the pressure of the tool being bolted to it,
02:26 PM gloops: only one way to find out, i dont suppose you could just throw it away without tying
02:26 PM gloops: trying
02:26 PM fragalot: if it's almost all the way cracked through; nothing to lose imho
02:27 PM gloops: nope lol, ive been waiting fo it to part but just managed the last job i did still intact
02:28 PM fragalot: that last inch is just so you don't have to clamp it up whilst welding :D
02:28 PM fragalot: the lamello Zeta P2 is one weird mechanism
02:29 PM gloops: yeah i want to save that heh, you can drill and tap it all way along, insert mild steel threaded rod, then weld either side of the line of mild steel rods, would kind of dovetail it and clamp it shut, but i dont think ill go to those lengths
02:32 PM gloops: biscuit jointer?
02:33 PM fragalot: with a twist
02:34 PM fragalot: once the blade has reached final depth it kinda 'bounces' up and down to create a channel at the rear of the biscuit pocket
02:34 PM fragalot: so you can slip in removable joining thingymajiggers that lock into the channel
02:34 PM fragalot: https://www.youtube.com/watch?v=rTElcjiiIto
02:36 PM gloops: hmm just reading that
02:36 PM gloops: the downside seems to be that the t slot weakens the joint
02:37 PM fragalot: oh brilliant
02:37 PM fragalot: my tv just updated and installed this "Samba TV" thing
02:38 PM XXCoder: dang
02:38 PM fragalot: which apparently recognizes on-screen content and suggests other pieces of dreg on
02:38 PM XXCoder: contractors is very good on spacking.
02:38 PM gloops: although the connectors are tough and clamp together well, the special shaped cut out does not leave much material between the centre and edge of the panel. The result is that the board is weakened considerably at the joint and given to breaking when force is applied from either side. Dominos and glue or confirmat screws are stronger.
02:39 PM fragalot: gloops: at some point though, the practical strength is more than sufficient
02:39 PM fragalot: would I use these to build a staircase? hell no.
02:40 PM fragalot: would I use that for a simple bookshelf? Absolutely.
02:40 PM gloops: id imagine the weakness will go away the bigger size biscuits are used
02:40 PM fragalot: the golden rule of biscuits: use the largest that will fit :P
02:41 PM XXCoder: lol
02:41 PM jdh: I like flakey grands biscuits
02:43 PM gloops: im not really a biscuit connoisseur i eat any
02:43 PM XXCoder: flakey dont sound like good grip between parts ;)
02:47 PM gloops: any date in mind for the pouring fragalot?
02:51 PM fragalot: gloops: nope.
02:52 PM fragalot: going on holiday for a week on friday, will probably order the metal plates after that
02:52 PM fragalot: let's just say it's a good job i'm not in a hurry because this is starting to become one of my longest running projects :)
02:55 PM gloops: lol, i know the feeling
03:17 PM gloops: hmm, photos of the great wall being started - funny this coincides with steel tariffs heh, gonna be a lot of steel going into that
03:28 PM Tom_shop: great wall of chamerica?
03:29 PM fragalot: it's going to be the greatest
03:29 PM fragalot: longest wall ever built
03:29 PM fragalot: fantastic.
03:29 PM fragalot: you'll love it
03:29 PM Tom_shop: i haven't been keeping up on it
03:29 PM Tom_shop: so they'll have to swim around it then?
03:29 PM fragalot: or dig under, or get a ladder
03:30 PM fragalot: or walk around
03:30 PM Tom_shop: they already dig under
03:30 PM Tom_shop: well, i got my way covers fixed
03:30 PM gloops: some photos on twitter, looks like substantial iron railings about 16 feet high
03:30 PM Tom_shop: i used some old material and it had a tear in it to start with but was all i had the right width
03:31 PM gloops: what have you made, something like bellows Tom?
03:31 PM Tom_shop: so i went back to the place i got the new stuff from and they gave me another piece but this is 1/8" instead of 1/16"
03:31 PM Tom_shop: no
03:31 PM Tom_shop: this works great really
03:31 PM Tom_shop: easy to clean off too
03:31 PM Tom_shop: unlike bellows would be
03:32 PM Tom_shop: not pretty but very functional
03:32 PM gloops: best way
03:32 PM Tom_shop: just flat neoprene
03:33 PM Tom_shop: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Way_Cover.jpg
03:34 PM Tom_shop: i moved that piece to the back and stuck the 1/8" in it's place
03:34 PM Tom_shop: stiff enough it doesn't hang on the pillowblock under it
03:34 PM Tom_shop: the other would hang every now and then
03:34 PM gloops: wont get tangled up
03:34 PM fragalot: i have something similar on my rf45
03:35 PM fragalot: still gets chips underneath it though so I need to get something wider
03:35 PM XXCoder: tom nice progress!
03:35 PM Tom_shop: these guys are nice, they gave me the last 2 pieces
03:35 PM Tom_shop: but they deal in huge rolls of it
03:35 PM gloops: thats like car inner tube material right?
03:35 PM Tom_shop: tall as a forklift
03:35 PM XXCoder: Tom_shop: home basement had a very nice progress this week sof ar. we finished off all of walls, and contractors finished spacking it
03:35 PM Tom_shop: yeah
03:36 PM gloops: butyl we call it
03:36 PM XXCoder: later they will orange peel the walls
03:36 PM Tom_shop: nice
03:36 PM Tom_shop: the stuff i had was really old and stiff but i tried to use it
03:36 PM XXCoder: plumber coming today, to see wtf going on with sewers
03:36 PM Tom_shop: turd stuck?
03:37 PM gloops: lol
03:37 PM Tom_shop: :)
03:37 PM XXCoder: no problems worse than that
03:37 PM XXCoder: clothes washer output goes to downstairs tub
03:38 PM XXCoder: and sometimes sewer gets blocked with no reason
03:38 PM Tom_shop: missin some socks?
03:38 PM XXCoder: lol
03:38 PM gloops: get the rods down it
03:39 PM Tom_shop: i should line my toolbox with this stuff, i got enough extra
03:39 PM XXCoder: we may have to pull tub and toilet thats why we are not finishing restroom off till later.
03:39 PM Tom_shop: i'll keep it for repairs though
03:39 PM XXCoder: its still missing sink, sections of walls
03:40 PM gloops: if its clay pipes just hope a pipe hasnt collapsed under something important
03:40 PM fragalot: you could say that it's ... crapped out.
03:41 PM gloops: you can get that from roof supplies Tom, or if you see any contractors doing a flat roof, usually plenty of offcuts
03:41 PM gloops: about £8 square metre here
03:41 PM fragalot: gloops: you have just reminded me that I have 2 big rolls of the stuff lying about doing nothing good!
03:41 PM fragalot: if I can remember this by tomorrow I'll cut some larger pieces off for my mill
03:42 PM Tom_shop: gloops, get what?
03:42 PM gloops: that rubber
03:42 PM Tom_shop: these guys do elevator conveyors etc, they have plenty of the stuff
03:42 PM Tom_shop: grain elevator
03:42 PM XXCoder: yes, lots rubbers lol
03:43 PM gloops: ive got some offcuts, i might use it to line mine with, it is easy to clean and tough
03:46 PM gloops: well when i say clean, if you bang it the sawdust falls off lol
03:47 PM Tom_shop: yep

05:27 PM Tom_L: find old frenchfries and half eaten burgers?
05:30 PM JT-Shopp: your supposed to clean a car?
05:31 PM skunkworks: mostly frenchfries I think...
05:31 PM skunkworks: This thing has 200K and the original clutch.. I think I am an awesome driver :)
05:31 PM JT-Shopp: those little buggers
05:31 PM JT-Shopp: what is it?
05:33 PM JT-Shopp is now known as JT-Shop
05:33 PM CaptHindsight: anyone heard from archivist lately?
05:33 PM Tom_L: no
05:33 PM Tom_L: they asked in dev the other day
05:33 PM CaptHindsight: archivist_herron: is still logging I believe
05:34 PM Tom_L: 01:02 PM Tom_L: February 4 2018 09:53 AM archivist: docs for gmoccapy that point to vids are not very usable for offline use
05:36 PM CaptHindsight: didn't someone say he was working on some project a few weeks ago
05:36 PM Tom_L: no idea
05:36 PM CaptHindsight: but it been more weeks since then
05:36 PM CaptHindsight: maybe someone should knock on his door?
05:39 PM CaptHindsight: pretty sure here lives somewhere around here https://goo.gl/maps/H5FP8wHmFN12
05:50 PM mozmck: Anyone know if "apt install" saves the packages it downloads somewhere? "apt-get install" saves them to /var/cache/apt/archives, but "apt install" does not.
06:12 PM Tom_L: mozmck, https://askubuntu.com/questions/178806/where-do-packages-installed-upgraded-with-apt-get-stored?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa
06:14 PM Tom_L: that's not much help :(
06:14 PM mozmck: Tom_L: yes, but the newer "apt" command does not store the packages there. I can't find any information on if or where it stores them.
06:14 PM Tom_L: what about apt cache?
06:15 PM mozmck: Thanks for looking though.
06:15 PM mozmck: I don't know - what does that do?
06:15 PM Tom_L: The .deb-files you have allready downloaded are stored in /var/cache/apt/archives/ . /var/cache/apt/archives is where they should be stored. You can backup all the *.deb, then copy it into vmware, you can copy it in /root/sw_backup . The folder can not be /var/cache/apt/archives/

09:46 PM Xnke: evenin' folks
09:47 PM Xnke: I'm building a new double-column style mill, and am researching CAM programs
09:47 PM Xnke: I use Solidworks for drawing, am lucky enough to have a mostly full seat with a perpetual license for 2007
09:47 PM Xnke: so as long as I don't upgrade it's good
09:48 PM Xnke: But I need to figure out a CAM system, postprocessor, and stepping motor controller
09:49 PM Tom_L: fusion 360
09:49 PM Xnke: I built a little 3-axis parallel port controller a decade ago using Allegro free samples, but output power is limited and it's pretty crudely made
09:49 PM Tom_L: linuxcnc with mesa hardware is pretty hard to beat
09:49 PM Xnke: I've looked at fusion360-does it require internet access like the other autodesk stuff?
09:49 PM Tom_L: yes it's cloud based
09:50 PM Xnke: won't work then-no internet access at the shop
09:50 PM Xnke: so linuxcnc with mesa hardware-I'll look into mesa
09:50 PM Tom_L: freecad for linux is making improvements
09:51 PM Xnke: I've used linuxEMC once before but I only got it to work once and then didn't bother with it after that
09:51 PM Xnke: what are people here using for controllers, and what kind of machines?
09:51 PM Tom_L: pc with mesa cards
09:52 PM Tom_L: running linuxcnc
09:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Mister_plumbing2.jpg
09:52 PM Tom_L: that's one i built
09:53 PM hazzy-dev: Xnke I use solidworks with the HSMWorks CAM plug in, about the best combo out there I think
09:55 PM hazzy-dev: I wonder if you can find an old enough version of HSMworks to run on SW 2007, that is starting to be pretty old ...
09:56 PM Xnke: yeah, that's the issue
09:56 PM Xnke: I could probably find an old version of CAMWorks or SolidCam
09:56 PM Xnke: but I'm sure I'd have to re-up the maintenance on solidworks to get it
09:57 PM Tom_L: can't help much there, i'm using an old version of smartcam i've had for years
09:57 PM hazzy-dev: GibsCAM is also good, but it takes a little longer to program a part than in HSMW
09:57 PM Xnke: which now, because Dassault is completely off the rails, means you have to pay the maintance fees for the entire time since it lapsed. So, I'd have to pay 11 years of maintenance
09:57 PM Xnke: and then, I'd loose my perpetual license and go to a subscription
09:58 PM Tom_L: that's why i use what i use
09:58 PM Xnke: I've been looking at CamBam, which is super cheap if it's what I can use
09:59 PM Tom_L: i looked at it once
09:59 PM Tom_L: i'm not using it.
09:59 PM Xnke: 149$ for a full license, but I am not sure it will do the kind of machining I want to do
09:59 PM Tom_L: what do you want to do?
09:59 PM Tom_L: 3d?
09:59 PM BitEvil is now known as SpeedEvil
09:59 PM XXCoder: theres estlcam, its not wow but works
09:59 PM Tom_L: 2.5?
09:59 PM XXCoder: its mostly 2d, though 2.5 and 3d is possible
10:01 PM Xnke: Most of what I will do is 2.5D, but there are a lot of parts that seem like I would need full 3D control
10:01 PM Xnke: A lot of flat brackets and aluminum flanges
10:02 PM Tom_L: sounds like 2.5d would be enough
10:02 PM Xnke: but some of those flanges need transition tapers, or if I get super ambitious I may try to do elliptical radius air horns
10:02 PM XXCoder: anything 3d can be done with 2.5d with 2 steps
10:02 PM Xnke: I am also considering a rotary 4th axis for indexing, for cutting splines
10:03 PM Xnke: So for a full 3d contoured part, I would run a roughing cut and then a finish cut with 2.5d control?
10:05 PM Tom_L: http://linuxcnc.org/docs/2.7/html/gui/ngcgui.html
10:05 PM Xnke: I feel like I've totally skipped a class at school, I ran the big CNC machines at college with no problems-but I never learned all the "how it works" details before leaving
10:06 PM Xnke: Just the draw-cam-gcode on a disk, plug disk in and load the pallet
10:08 PM Tom_L: building a small gantry?
10:10 PM Xnke: https://i.imgur.com/agG5C4P.jpg
10:10 PM Xnke: Fixed column, table moves on the Y axis
10:11 PM Xnke: Z axis is carried on the X
10:11 PM Tom_L: what do you plan to cut with it?
10:11 PM Xnke: Waiting on the motion control hardware, one more chunk of plate, and the casting for the table to season a bit more
10:11 PM XXCoder: isnt fixed gantry better for spindle rigidity?
10:11 PM XXCoder: but weaker on Y?
10:12 PM Xnke: Aluminum, 99% of the time. Steel if it turns out rigid enough
10:12 PM Tom_L: i'm pretty happy with mine so far
10:12 PM Xnke: The big empty section in the middle of the base is being filled with polymer concrete
10:12 PM XXCoder: nice
10:13 PM Xnke: There is an insert plate that ties into the T-slot extrusions, and provides a place for the linear bearing blocks to bolt to
10:13 PM Xnke: The blocks are fixed, they do not move with the table, and the rails bolt to the underside of the table
10:13 PM Xnke: That way, since the spindle only traverses left to right, the point of maximum table support is always directly under the spindle
10:15 PM XXCoder: nice
10:17 PM Xnke: The two column uprights are from a slab of 16mm thick Fortal-HR plate I salvaged from the scrapyard
10:18 PM Xnke: I gave 8$ for the section of plate, and had to borrow a bigger truck than my S-10 to bring it home
10:18 PM Xnke: UTS is 78ksi, hardness is brinell 150B
10:18 PM Xnke: so a slight bit harder than mild steel and an extra 30ksi tensile strength
10:19 PM Xnke: Other than the whole plate being scummy from being out in the weather, it's been one of my best scores ever at the yard.
10:20 PM Xnke: all that extrusion came from the same yard, there is about 50lbs more off the frame to the left.
10:20 PM Xnke: This is an example of what I want the machine to do
10:20 PM Xnke: https://i.imgur.com/UzrYBfq.jpg
10:21 PM Xnke: That is an intake for a Nissan L20B engine-the flange there was waterjet cut from plate, at an exhorbant cost-even though the plate was next to free
10:22 PM Xnke: I'd love to be able to batch up a 12x18" plate, hit "go" on the mill, and have it cut out four intake flanges while I am cutting runner tube and injector rails
10:22 PM ziper: how exorbitant
10:28 PM Xnke: Probably gonna be a long way off, I figure I'll have to babysit the machine for a while before I trust it to run semi-unattended
10:32 PM Xnke: Tom_L do you run coolant on your machine?
10:34 PM Tom_L: yes, mist
10:34 PM Xnke: That's the style I'm looking at myself
10:34 PM Xnke: How much runoff do you get from the mist? I am planning to have a gutter on the table, and then additional gutters in the base
10:35 PM Xnke: just run it all off back into the basin
10:36 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Coolant_Drain1.jpg
10:36 PM Tom_L: cut a trench around the edge
10:36 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Coolant_Drain2.jpg
10:36 PM Tom_L: drains into a 'bucket' hanging off the back
10:37 PM Xnke: Yep. I planned on running the T-slot table with a surrounding gutter like you've done
10:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Chip_Guard2.jpg
10:37 PM Xnke: and then letting it drip into the molded in gutter in the epoxy granite base
10:37 PM XXCoder: ohh nice Tom_L
10:37 PM XXCoder: so, when will you ship it to me?
10:37 PM Tom_L: i catch it in a plastic bucket so i can pour it back into the gal jug it comes from
10:38 PM Tom_L: XXCoder, i though you've seen it
10:38 PM XXCoder: not the new plastic addons
10:38 PM Tom_L: i've got different ones now
10:38 PM Xnke: I'm thinking a 1/2" pipe down into the coolant reservoir with the lift pump would be the way I go
10:38 PM Tom_L: that back one is cardboard
10:38 PM Tom_L: but not now
10:39 PM Tom_L: got some polycarbonate
10:39 PM Xnke: that was the next question about the mist system
10:39 PM Tom_L: and thin stuff i cut different sizes to block the back when i'm not using all of it
10:39 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Mister1.jpg
10:40 PM Tom_L: $5 chinaco mister
10:40 PM Tom_L: works ok
10:40 PM Tom_L: $5 worth for sure
10:40 PM Xnke: I'm planning on running a torpedo heater nozzle, the lift pump just has to make 1psi or less, the compressed air will draw and atomize from there
10:41 PM Xnke: only because I have a big box of them, they are pretty nice calibrated venturi atomizers
10:42 PM Xnke: What size of linear rail are you using, Tom?
10:42 PM Tom_L: umm 15mm?
10:42 PM Tom_L: iirc

10:51 PM Tom_L: i'd have to go look
10:51 PM Xnke: I am planning on 25mm rails from Automation Overstock
10:51 PM Xnke: gonna be roughly 125$/axis
10:52 PM Tom_L: should be plenty heavy
10:52 PM Tom_L: these are
10:52 PM Tom_L: i didn't want the round rails
10:53 PM Xnke: well, going by commercial professional machines
10:53 PM Xnke: they want to load the rails and bearing blocks to about 2-5% of the ultimate ratings of the rail/block
10:54 PM Xnke: so I figure I can't do worse than that, 25mm rails are just as cheap as 20mm, and 30mm not that much more
10:54 PM Xnke: so 25's it is
10:54 PM Tom_L: i cut one of them down
10:54 PM Xnke: When it comes to actually building the machine, I got that part in the bag
10:55 PM Xnke: it's the control software and controller that seem to be the part I don't know enough about
10:55 PM Tom_L: ppl here can help
10:56 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Control2.jpg
10:56 PM Tom_L: i pretty much built everything from scratch
10:57 PM Tom_L: mesa hardware is the way to go
10:57 PM Xnke: That's what I'm looking at too, the actual drivers are no big deal
10:57 PM Xnke: I'm looking at using the arduino GRBL stuff, for niceness of USB control
10:57 PM Tom_L: mine runs off the parallel port but there are other options
10:57 PM Xnke: just can't find a serious machine using it
10:57 PM Tom_L: baaah
10:57 PM Tom_L: no
10:58 PM Tom_L: has serious limitations
10:58 PM Xnke: It provides everything every other board out there does, but the g-code limitations seem not worth the trade off
10:58 PM Tom_L: i've got a friend that uses it but i won't
10:59 PM Tom_L: are you gonna run steppers or servos?
10:59 PM Xnke: I also looked at those 140$ 4-axis controllers on ebay, based on the TB6600 drivers..but I have heard horror stories about the design
10:59 PM Xnke: Steppers
10:59 PM Tom_L: i'm using gecko stepper drivers
10:59 PM Tom_L: with mesa hardware
10:59 PM Tom_L: mine are the 203v geckos
10:59 PM Tom_L: pretty hard to beat
10:59 PM Tom_L: there are cheaper options
11:00 PM Xnke: no kidding
11:00 PM Xnke: the actual silicon in a gecko driver is about 4 bucks
11:00 PM Xnke: but the convenience
11:00 PM Tom_L: they've got things others lack
11:00 PM Xnke: it's tempting but expensive. I'm looking at the G540
11:01 PM Tom_L: it will work but there's a quirk about it i forget what it is...
11:01 PM Tom_L: but they will work
11:01 PM Xnke: the problem is it's all parallel port driven
11:01 PM Tom_L: i preferred the 203v
11:01 PM Xnke: which is quite frankly crap, IMO
11:01 PM Tom_L: what is?
11:01 PM Xnke: parallel port control
11:02 PM Xnke: it's 15 years out of date at best
11:02 PM Tom_L: no, you can do ethernet
11:02 PM Xnke: I was talking about the G540 and similar
11:02 PM Tom_L: i just had a parallel port to start with so i went that way
11:02 PM Tom_L: that's just the stepper driver
11:02 PM Xnke: but it really does seem that 99% of the controllers out there are either Arduino based or parallel port base
11:02 PM Tom_L: cheap
11:03 PM Tom_L: they run mesa and linuxcnc on commerial machines
11:07 PM Tom_L: just depends what you want
11:10 PM MarkusBec: mesa card with trinamic stepper driver and all the detection features would be nice
11:10 PM MarkusBec: spi mode
11:11 PM MarkusBec: no lost steps and load detection
11:22 PM Xnke: one of the things I am considering as a "need" over a "want" is a spindle that can do tapped holes
11:22 PM Xnke: which tends to be a servo-driven spindle
11:31 PM Tom_L: yeah, i'm slowly looking down that path too
11:31 PM Tom_L: low end torque
11:38 PM hazzy-dev: Xnke: I ran my decent sized bed mill with GRBL for about 2 days and it worked fine with most CAM generated code, but I was limited to about 60ipm rapids and by the very limited implementation of RS274.
11:38 PM hazzy-dev: But GRBL is dirt cheap and simple to set up so just do it(tm) and if/when it limits you, look into mesa hardware etc.
11:38 PM hazzy-dev: Even though I used it for such a short time it was well worth the few hour of time and about 20$ I spent trying it out.
11:38 PM hazzy-dev: gn8
11:40 PM Tom_L: i skipped that step :)
11:48 PM fragalot: hi
